Abstract

A tamper-evident product and related methods of production. A container includes a neck, and a tamper-evidencing component separate from the container and carried by the neck of the container in direct contact with a corresponding portion of the container neck. The component is composed of material that has higher thermal conductivity than that of a material of the container so as to concentrate heat in the corresponding portion of the container neck. The neck is thermally responsive to application of heat pursuant to tampering with the product by at least one of the following responses: an irreversible change in visual appearance of the corresponding portion of the container neck, or fracture of the container neck at the corresponding portion of the container neck.

First claim

The invention claimed is:

1. A product that includes:
a glass container including a neck; and
a metal component carried in contact with a corresponding portion of the container neck, such that heating of the product pursuant to product tampering results in at least one of discoloration of the container neck or fracture of the container neck.

2. The product set forth in claim 1 , wherein the metal component is a ring.

3. The product set forth in claim 1 , that also includes an anti-refill fitment carried in the neck to deter refill of the container and at least partially composed of plastic, wherein the metal component is carried by at least one of the container neck or the fitment.

4. The product set forth in claim 3 , wherein the fitment includes an outer wall carrying the metal component in direct contact with an interior surface of the container neck.

5. The product set forth in claim 1 , wherein the container is composed of a base material and a thermally responsive material carried by the base material that changes in appearance upon said heating.

6. The product set forth in claim 1 , wherein the metal component is embedded in an external surface of the container neck.

7. The product set forth in claim 6 , wherein the metal component is carried in a preformed groove of the external surface of the container neck.

8. The product set forth in claim 6 , wherein the metal component is insert-molded in the external surface of the container neck.

9. The product set forth in claim 1 , wherein the metal component is a snap ring carried in an interior of the container neck.

10. A method of producing a product that includes:
(a) flowing liquid into a glass container having a neck;
(b) non-removably coupling an anti-refill fitment into the neck of the container to render the product non-refillable; and
(c) coupling a tamper-evidencing metal component to at least one of the fitment or the container neck so that the component is in direct contact with a corresponding portion of the container neck, such that heating of the product pursuant to tampering concentrates heat in the component and in the corresponding portion of the container to result in at least one of discoloration of the container neck or fracture of the container neck.

11. The method set forth in claim 10 , wherein the tamper-evidencing component is a metal ring.

12. The method set forth in claim 11 , wherein the metal ring is a snap ring carried in an interior of the container neck.

13. The method set forth in claim 10 , wherein the fitment includes an outer wall carrying the tamper-evidencing component in direct contact with an interior surface of the container neck.

14. The method set forth in claim 10 , wherein the container is composed of a base material and a thermally responsive material carried by the base material that changes in appearance upon said heating.

15. The method set forth in claim 10 , wherein the container is a glass container, the fitment is at least partially composed of plastic, and the tamper-evidencing component is a metal component carried in at least one of the neck of the container or the fitment and in contact with a corresponding portion of the container neck.

16. A product produced by the method set forth in claim 10 .

17. A method of producing a product that includes:
(a) forming a glass container including a neck having an outer surface; and
(b) embedding a tamper-evidencing metal component in the container neck, such that the metal component is carried in contact with a corresponding portion of the container neck, such that heating of the product pursuant to product tampering results in at least one of discoloration of the container neck or fracture of the container neck.

18. The method set forth in claim 17 wherein the forming and embedding steps include insert molding the component to the container.

19. The method set forth in claim 17 wherein the forming step includes forming a recess in the outer surface, and the embedding step includes assembling the component in the recess and then applying glass solder over the component and adjacent portions of the container.

20. The method set forth in claim 17 , wherein the tamper-evidencing component is a metal ring.

21. The method set forth in claim 17 , that also includes coupling an anti-refill fitment to the container neck to deter refill of the container.

22. The method set forth in claim 21 , wherein the fitment includes an outer wall carrying the tamper-evidencing component in direct contact with an interior surface of the container neck.

23. A product produced by the method set forth in claim 21 .

24. The method set forth in claim 17 , wherein the container is composed of a base material and a thermally responsive material carried by the base material that changes in appearance upon heating.

25. The method set forth in claim 17 , wherein the tamper-evidencing component is a metal component carried in contact with a corresponding portion of the container neck, which is thermally responsive to application of heat pursuant to tampering with the product, via fracture of the container neck at the corresponding portion of the container neck or visible change in appearance of the container neck in response to transfer of heat from the metal component.
